The Chemistry of Coordination Complexes and Transition Metals


Book Description

This book covers all important nomenclature, theories of bonding and stereochemistry of coordination complexes. The authors have made an effort to inscribe the ideas knowledge, clearly and in an interesting way to benefit the readers. The complexities of Molecular Orbital theory have been explained in a very simple and easy manner. It also deals with transition and inner transition metals. Conceptually, all transition and inner transition elements form complexes which have definite geometry and show interesting properties. General and specific methods of preparation, physical and chemical properties of each element has been discussed at length. Group wise study of elements in d-block series have been explained. Important compounds, complexes and organometallic compounds of metals in different oxidation states have been given explicitly.

Inorganic Stereochemistry


Book Description

Molecular stereochemistry is a fundamental aspect of all areas of chemistry. It is especially important in inorganic chemistry where the coordination numbers are variable and occasionally quite high. The present book evolved naturally from a series of articles written by Professor Kepert for Progre88 in Inorganic Ohemi8try, elucida ting aspects of the stereochemistry of inorganic compounds of co ordination numbers 4-12. In the present volume, Professor Kepert has added new sections and synthesized these individual chapters into a unified treatment, updating his references when necessary to the most recent contributions in the literature, and inter weaving the various themes as deemed appropriate. The result is a major contribution, describing the stereochemistry of coordi nation compounds having both unidentate and multidentate ligands. The viability of the repulsion approach to stereochemistry is tested to the limit in this treatise and shown to be an extremely good way of rationalizing a diverse body of data.




Coordination Chemistry of Silicon


Book Description

The chemistry of silicon has always been a field of major concern due to its proximity to carbon on the periodic table. From the molecular chemist’s viewpoint, one of the most interesting differences between carbon and silicon is their divergent coordination behavior. In fact, silicon is prone to form hyper-coordinate organosilicon complexes, and, as conveyed by reports in the literature, highly sophisticated ligand systems are required to furnish low-coordinate organosilicon complexes. Tremendous progress in experimental, as well as computational, techniques has granted synthetic access to a broad range of coordination numbers for silicon, and the scientific endeavor, which was ongoing for decades, was rewarded with landmark discoveries in the field of organosilicon chemistry. Molecular congeners of silicon(0), as well as silicon oxides, were unveiled, and the prominent group 14 metalloid proved its applicability in homogenous catalysis as a supportive ligand or even as a center of catalytic activity. This book focuses on the most recent advances in the coordination chemistry of silicon with transition metals as well as main group elements, including the stabilization of low-valent silicon species through the coordination of electron donor ligands. Therefore, this book is associated with the development of novel synthetic methodologies, structural elucidations, bonding analysis, and also possible applications in catalysis or chemical transformations using related organosilicon compounds.

Low-Frequency Vibrations of Inorganic and Coordination Compounds


Book Description

During the course of far-infrared investigations of inorganic and coordina tion compounds at Argonne National Laboratory in the years 1962-1966, it became apparent that no suitable book existed which correlated and dis cussed the important vibrations occurring in this region for these molecules. Early in 1967 the initial steps were taken to write such a book. Then, in 1968, an excellent text by Professor David M. Adams entitled Metal-Ligand and Related Vibrations was published. At this point serious consideration was given to discontinuing work on this book. However, upon examination of Adams' book, it became clear that the references covered only the period to 1966. This field of research is accelerating so tremendously, and the period 1966-1969 has seen so many new studies, that upon reconsideration it was decided to continue writing this text. The references in this book, particularly in the last several chapters, include many papers published in 1969. However, the proliferation of the far-infrared literature has made it impossible to present all the published material that has any bearing on the subject. Many titles do not pertain primarily to the far-infrared region as such, and some of this research has been omitted for this reason. Organometallic compounds have been neglected since the author feels that adequate reviews of that subject are available. Other studies may be missing simply because, owing to space limitations, only the more important researches could be considered. Of course, "importance" may, in this case, reflect the author's interest and prejudices.

Introduction to Coordination Chemistry


Book Description

At the heart of coordination chemistry lies the coordinate bond, in its simplest sense arising from donation of a pair of electrons from a donor atom to an empty orbital on a central metalloid or metal. Metals overwhelmingly exist as their cations, but these are rarely met ‘naked’ – they are clothed in an array of other atoms, molecules or ions that involve coordinate covalent bonds (hence the name coordination compounds). These metal ion complexes are ubiquitous in nature, and are central to an array of natural and synthetic reactions. Written in a highly readable, descriptive and accessible style Introduction to Coordination Chemistry describes properties of coordination compounds such as colour, magnetism and reactivity as well as the logic in their assembly and nomenclature. It is illustrated with many examples of the importance of coordination chemistry in real life, and includes extensive references and a bibliography. Introduction to Coordination Chemistry is a comprehensive and insightful discussion of one of the primary fields of study in Inorganic Chemistry for both undergraduate and non-specialist readers.
